In recent years, the learnability of rational expectations equilibria (REE) and determinacy of economic structures have rightfully joined the usual performance criteria among the sought-after goals of policy design. Some contributions to the literature, including Bullard and Mitra (2001) and...

We examine learning, model misspecification, and robust policy responses to misspecification in a quasi-real-time environment. The laboratory for the analysis is the Sargent (1999) explanation for the origins of inflation in the 1970's and the subsequent disinflation. Three robust policy rules...

In his monograph The Conquest of American Inflation, Sargent (1999) points out the perils of econometric policy evaluation of the Theil-Tinbergen tradition wherein one estimates a reduced form econometric model of the economy and subjects it to control. If the model is misspecified, as is...

In the late 1960s and into the 1970s, the United States experienced a burst of inflation the origins of which seemed hard to uncover. This paper advances the idea that the Fed simply got the model wrong. We assume that the true model of the economy is a variant of the standard New Keynesian...
